SURFER FOR SCIENTIFIC APPLICATION

Surfer is a package for interactive graphic analysis of functions of two variables. A function has to be given as an ASCII disc file having a matrix structure. The function can be displayed in the form of a three dimensional (surface) or a two dimensional (map) image.

The two-dimensional image in turn may be of two types: in the form of isolines of the specific levels, drawn by the set of the colors and in the form of topographic map, where the gradual transformation of colors from a rather wide spectrum takes place.

In course of analysis a user may interactively apply the well known graphic tools such as rotation, color fitting, layer cutting, zooming, and measurung. All forms of image may be put out into the PostScript files and printed out onto the laser printer.
